Connecting at John Wayne airport

Connection time calculator, immigration and security, and how to move between terminals at SNA.

How connections work at SNA

At Orange County John Wayne airport, as at every airport in the United States, passengers arriving on an international flight must clear immigration (CBP) and customs, collect their checked bags and re-check them, and go through TSA security again before their connecting flight, even when both flights are on the same ticket.

The airport has 3 terminals or concourses (Terminal A (Air Canada, American, Breeze, Delta, WestJet), Terminal B (Alaska, United), Terminal C (Allegiant, Frontier, Southwest)). All of them are connected after security, so you do not need to clear security again to change.

Terminals / concourses: Terminal A (Air Canada, American, Breeze, Delta, WestJet), Terminal B (Alaska, United), Terminal C (Allegiant, Frontier, Southwest)

Getting between them: Walking airside between gates (about 10 minutes at most)

All the gate areas inside the secure area are connected, so you can change terminal without going through security again. International arrivals clear immigration and customs in a separate area on the lower level of Terminal C.

  • Arriving on an international flight, you clear immigration and customs in Terminal C before connecting to a domestic flight.

Estimate based on typical times at this airport, not your airline's official minimum connection time. Immigration and security lines change with the time of day and season. On a single ticket, the airline must rebook you if you miss the connection; on separate tickets, it does not.
